The following changes are made to align the order with current NOTAM policies/processes and to ensure compliance with ICAO standards and contractions. These changes include modifying the acronym NOTAM from Notice to Airmen to the more applicable term Notice to Air Missions. Changes to Field Conditions (FICON) Reporting have been made regarding updated requirements for Runway Condition Codes (RwyCCs) NOTAMs, added verbiage that FICON must not be issued for a closed runway, and added verbiage stating RwyCCs are reported based on direction of assessment allowing for only one set of RwyCCs per runway. This change removes breaking action report of “good" as NOTAM criteria. This change also removes the reference to the 28-day publication cycle for International and Domestic Notices. Changes to permanent NOTAM procedures have been included. Added verbiage to allow for Simplified, Short ALS with Runway Alignment Lights temporarily changed as NOTAM criteria. Previously, unserviceable was the only option which did not accurately describe the reduced condition of the ALS. Changes also include updated United States NOTAM Office (USNOF) roles and responsibilities. This change sets the same NOTAM criteria for both Automated Surface Observing System (ASOS) and Federal Automated Weather Observation System (AWOS) regardless of who maintains them. This change also updates and makes editorial changes to publications related to this order.

b. 2-1-4. DOMESTIC NOTICES AND INTERNATIONAL NOTICES

This change removes the reference to the 28-day publication cycle in the paragraph concerning International Notices and Domestic Notices to reflect the transition to on-demand publication of these notices, effective May 20, 2021.

c. Editorial Changes

Las Vegas McCarran International was changed to Las Vegas Harry Reid International in Appendix A.

d. Entire Publication

Additional editorial/format changes were made where necessary. Revision bars were not used because of the insignificant nature of these changes.
